This is a run through what it takes to drive the AWD hybrid Fiero and how to drive it in different modes. I built this car for the Grassroots Motorsports $2009 challenge, with a total investment of about $1800.

Fiero electric motor transaxle first test
This is a major milestone in my 1986 Pontiac Fiero electric car conversion
project. After numerous delays getting the correct adapting hardware for
the new motor to the old transaxle, we finally mounted the clutch and motor
assembly onto the transaxle and frame of the car. With everything in place,
I applied a regular 12 car battery to the motor and amazingly, it ran
without a hitch! See my website (www.roboticmayhem.com) for more
information on this project.

video documentation of the process along with a few test drives. It runs on
12, 12 volt Trojan deep cycle lead acid batteries. Powered by a 9.1 in.
dia. Advanced DC motor with a 500 amp Curtis controller. Part 2 and 3 will
be coming soon. GO ELECTRIC!

This machine is FUN, crazy torque!
FAQ-Top speed: 70 tested (it'll go higher) Range: 11 mi tested (it'll do
more) 0-60: not yet tested. Burnouts: yes. Powerslides: absolutely. Still

How Diff Lock Works and When To Use It (UK Terminology, Land Rover)
This video instructs the viewer on how the standard *CENTRE* "diff lock"
works in a permanent 4 wheel drive (4x4) vehicle, a Land Rover in this
case, and gives an idea for how and when to use it.
A Land Rover Discovery was the vehicle featured in the demonstrations, but
this video applies to any 4x4 vehicle with a center diff lock.
In summary, diff lock (whether it be the centre diff lock fitted as
standard or front/rear aftermarket diff lock) is useful in slippery
situations such as snow, ice and mud.
Pontiac Fiero GT--D&M Motorsports Walk Around Review
Pontiac Fiero GT Video Review Presented by D&M Motorsports.
The Pontiac Fiero is a mid-engined sports car that was built by the Pontiac
division of General Motors from 1984 to 1988. The Fiero—meaning "proud"
in Italian and "wild", "fierce", or "ferocious" in Spanish—was designed
by George Milidrag and Hulki Aldikacti as a Pontiac sports car. The Fiero
was the first two-seater Pontiac since the 1926 to 1938 coupes, and also
the first and only mass-produced mid-engine sports car by a U.S.
manufacturer. Many technologies incorporated in the Fiero design such as
plastic body panels were radical for its time. Alternative names considered
for the car were Sprint, P3000, Pegasus, Fiamma, Sunfire, and Firebird
XP. The Fiero 2M4 (2-seat, Mid-engine, 4-cylinder) was on
Car and Driver magazine's Ten Best list for 1984. The 1984 Fiero was the
Official Pace Car of the Indianapolis 500 for 1984, beating out the new
1984 Chevrolet Corvette for the honor.
370,168 Fieros were produced over the relatively short production run of
five years; by comparison, 163,000 Toyota MR2s were sold in its first five
years. At the time, its reputation suffered from criticisms over
performance, reliability and safety issues. Today however, compared to less
adventurous attempts at two-seaters such as the Ford EXP, the unique style
of the Fiero compared to other American cars has left it a cult following
as a collectible car. It remains a popular chassis for rebodies and
Already selling the Corvette, General Motors management and accountants
were opposed to investing in a second two-seater sports car. But in 1979,
during the oil crisis, management saw a market opportunity for a
fuel-efficient sporty commuter car, and design work on the Fiero commenced.
To this end, it was fitted with a fuel efficient version of GM's 2.5 L
four-cylinder "Iron Duke" engine capable of 27 mpg-US (8.7 L/100 km; 32
mpg-imp) in the city and 40 mpg-US (5.9 L/100 km; 48 mpg-imp) on the
highway with the economy-ratio transmission option. These figures are U.S.
Environmental Protection Agency test-circuit results, published by Pontiac,
and confirmed from multiple sources. It was impressive mileage for a
2.5-liter engine of the period, and still good by today's standards, but
the three-speed automatic reduced highway mileage to only 32 mpg-US (7.4
L/100 km; 38 mpg-imp). With respect to fuel economy, the Fiero would appeal
to a market niche for which the Corvette with its V8 engine was unsuitable.
A mid-engine layout was chosen as a way to reduce both aerodynamic drag and
vehicle weight to improve fuel efficiency, and also for its handling,
traction, and braking benefits. The sports car potential of the mid-engine
layout was not fully realized when the Fiero debuted. In line with its
market position, the tires, brakes, and some suspension components were
carried over from other GM economy cars (like the Chevrolet Citation and
Chevrolet Chevette) so the Fiero could be priced appropriately. As a
result, the handling and cornering abilities of the initial Fiero were
merely on par with other contemporary sporty coupes (Road & Track 1985).
The public had high expectations for the Fiero with its mid-engine layout
and futuristic styling, which resembles more exotic mid-engine sports cars
costing much more. While initially garnering good reviews for its handling
(Motor Trend 1984), the Fiero soon received disappointing reviews, as the
automotive critics expected higher performance from a mid-engine
two-seater. Despite the critical press, the Fiero sold extremely well and
Pontiac operated three shifts at the factory during 1984, and could not
keep up with initial demand.
The sharing of suspension components with other GM cars meant the rear
suspension and powertrain was almost identical to that of the Chevrolet
Citation and Pontiac Phoenix; the Fiero even included rear tie rod ends
attached to a "steering knuckle", although these were hard-mounted to the
engine cradle and only used for maintaining the rear tire alignment. The
front suspension was derived from the Chevrolet Chevette, and Chevette
enthusiasts found that they could upgrade their undersized front brakes and
rotors using Fiero parts.
By 1985, the oil crisis was a thing of the past and demand developed for a
Fiero having more engine power and better sports car performance. Pontiac
responded by introducing the GT model which included upgraded suspension
tuning, wider tires, and a V6 engine having 43 horsepower (32 kW) more than
the base four-cylinder. In 1986, the GT model was restyled to look even

Initial Startup, running in the parking lot by my shop. A few donuts, a few
drifts and some straight line runs. A piss poor attempt to laying a patch!
My friends and I have spent over 400 hours building this car. It is caged
with race seats and harness belts. I plated the chassis and completely
rebuilt the back end of the frame to suit my driving needs! I used the
subframe from the Taurus SHO and modified it to fit the Fiero. I also
plated the subframe and added a 1/2" thick aluminum skidplate! This baby is
built to drive the piss out of it! :D
It will be interesting when I start running exotic blends of fuel, as I am
only starting off with some 87 Octane fuel to start with here. More to come

$2009 AWD Hybrid Fiero - First test drive!
First test drive with the $2009 AWD Fiero. The video shows the car in
electric only mode, it's so quiet that you can't even hear the motor over
the road noise from the nearby street! This was the first time the new
suspension has been driven on as well.

Flywheel Hybrid Technology
Torotrak is a UK-based company that's developing a technology called a
flywheel hybrid. Instead of using a big, heavy battery to store energy, the
Torotrak system uses a spinning flywheel. It's simple and lightweight
compared to traditional electric hybrids, and it's even going to be used in
Formula One race cars. There's no word yet if any automakers are signing
up, but if it starts winning races you can bet they'll be all over it.
